ELECTRIC MOTOR AND REGULATOR.

SPECIFICATION forming part of Letters Patent No. 404,583, dated June 4, 1889.

Application filed July 5, 1888. Serial No. 278,993. (No model.)

To (all whom io' 'nm/7j con/cern:

Be it known that I, ALFRED GARTNER, a subjectief the Empcrorof Austria-Hun gary, residin at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Electric Motors and Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othro ers skilled in the art to which it appertains to make and use t-he same, reference bein g had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to secure greater eiiiciency of power and provide a inore'simple and less costly motor; and it consists in the improved electric motor and in the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying` drawings, embraced in two sheets, in which like letters of reference indicate corresponding` parts in each of the several figures, Figure I is a side elevation of a motor and eo-operating parts, showing the same with but a part of the magnets usually employed therewith. Fig. 2 isa sectional view of the motor taken ou line ai, Fig. l. Figs. andi are detail views of the Iixed electro-magnets of said motor, and Figs. 5 and G are detail views ot certain revolving magnets. Figs. 7 and S are detail views of the commutator, Fig. 7 being a section taken on line y, Fig. l. Fig. 9 is a plan illustrating the connection of the electro-magnets with the commutator and the battery.

In said drawings, a indicates a suitable bedplate, which may be of wood, metal, or other suitable material, upon which frames b Z1, connected together by cross bars or pieces c e, are secured or formed. Said frames are approximately annular or provide a series of bearings at equal distances from a main shaft d, which latter extends centrally through said frames, substantially as shown in FigsA I and 2. Said shaft is arranged on bearings e and f, one of which consists of a post and screw 5oV e', the latter of which is provided with a socket to receive the conical end of the shaft and allow of a ready adjustment or removal of said shaft. Adjacent to the frames bl) the shaft d is provided with collars orwheels g g, which are connected by cross-bars 7L, extend- 55 ing parallel with said shaft and with the cross-pieces c e, or approximately so, and said cross-bars 7L provide bearings for a series of magnets 2'., which revolve with said shaft under the intluence of electro-magnetism.

On the cross-bars c c are arranged co-operating electro-magnets 7.: It; these are arranged to alternate with the movable electro-magnets, substantially as indicated in Fig. 1, so that the broad opposite faces of each of the movable magnets are presented to those of the fixed magnets as the said movable magnets revolve with the shaft. Said electro-magnets consist of soft-iron spools, as shown in Figs.

3, I, 5, and G, having broad end plates It" It" 7o and a hub 7112, all formed of one integral piece,

and winding-wires If", disposed between said end plates and extending oppositely through holes or passages la in said end plates. The

end plates being broad and the hub comparatively narrow in diameter, a deep receptacle is provided, adapted to receive a considerable number of windings of the wire and a proportionately great magnet-power in the soft iron. The peripheries of the end plates are So provided with suitable bearings or meanssuch as the'extensions 7e and screws or pins 7er-whereby the said end plates are secured on the frame of the motor or upon the bars 7L of the shaft.

The spools or magnet-plates are in series, both on the fixed cross-bars of the frames and on the shaft, and are connected as indicated or illustrated by Fig. 9, where the bars 7iy and c and the magnets thereon and connecting- 9o wires u a are laid out on a plane. I

The magnets are arranged in series on the frame and on the shaft in alternating and parallel planes, the revolving magnets moving in a path betweenthe fixed ones, so that tho broad end plates of the movable set of magnets are brought into close adjacency with those of the fixed ones, as will be understood upon reference to Figs. l and 2. y

The co1iducting-wires fu, as illustrated in loo said Fig. 9, convey the current from the ybattery m through 'the fixed magnets 1010,(01', if desired, through the movable ones in a reverse directiom) passing first through the series of spools on one cross-bar of the frame, and thus to the next series on the next adjacent cross,

bar, as indicated. From the said magnets lo the wires conduct the currentof electricity to a commutator or rheotrope n, (shown in Figs. 7 and 8,) by which the current is inverted.

Said commutator may be of any ordinary construction; but for purposes of economy and simplicity I prefer the one shown in Figs. l, 7, and 8.

From the commutator the electricity is transmitted to the revolving magnets, passing regularly through the succession of series, and 'from Athenceback 'to the-commutator, and from thence 'to the battery,as will be fclearlyfunderstood'upon referenceito '-Fig. 9.

Referring :now fto `the commutator'or rheoltrope whic'h I -prefer 4to employ, o 0" larestuds vcarrying-springs p p', .adapted vto lengage l'the 5 periphery of the commutator or 'rheotropelon .f the opposite sides thereof, as -indicated'in Fig. i 7. "Iherevolving vportion ofthe commutator' consists-in a disk -or plate q,of insulating A-fma- -terial-'suc'h as hard `rubber-around Whichf is-arranged a tubular section-ofbrassor-other `metal out ginto thefsiX parts vr r', more'or less, i

which ialternatelyconnect With-oppositepoles lof the circuit 'by means `of screws' ss', -`wires f ff, :and vfconducting-wires fa. Said 1oonductingf wires u lconnect one se't of alternate eparts, particularlytlhe `set marked r, with thecol 'lcction or group of revolving magnetsatone r end or :pole of said collection,rand 'theother set of :parts `r connect with the-opposite end-i o'f'said'collection, las indicated more particuflarly in Fig. i9.

The springs p p', whichengage lthe periph-i yeryof the commutatonfconnect, by meanso'f: 'su'it'able wires or-conductors u', vone vwith the? battery m, and through it with one pole of the fixed vmagnets,fand -the'other directly ywith the said series of 'fixed magnets lo.

yiron'thereof'being magnetized bythe-"current, and thus'saidrevolving 'magnets' are caused to move toward the fixed magnets k. This movement of the magnets t' causes the shaft d to revolve, and with it the commutator n. After ,passi n g through the revolvin g magnets the current passes to lthe screws s, thence through the wire t to the sections vor alternate parts r', and from thence to the spring p', then to the iixed magnets 7c, and again to vthe battery.

The motion of the commutator or rheotrope changes the relation of the parts r r to the i springs p p', andas a result the current changes, and thus the motion of the magnets lis continued, the'e'lfect of the reverse current being the same as is common -to this general class of motors.
